We are wondering if the new rate limit API applies to WFP; can we apply this to a dispatch and/or namespaced workers? This is not mentioned in the docs https://developers.cloudflare.com/workers/runtime-apis/bindings/rate-limit/

Cloudflare Docs

Rate Limiting

Define rate limits and interact with them directly from your Cloudflare Worker

Is there some realiable way to check if worker is avilable to be retrieved via stub and invoked? Seems like if I to deploy new worker (upload), and right away call dispatcher get on it to invoke it (fetch), I get gateway timeout. But if i wait few seconds before invoking fetch, it seems to work more reliably.

@Hard@Work | R2 any updates?

Vlad Lykhonis•10/3/25, 11:00 AM

On this page: https://developers.cloudflare.com/cloudflare-for-platforms/workers-for-platforms/platform/limits/ vs this page https://developers.cloudflare.com/durable-objects/platform/limits/

Does it mean if I deploy a Durable Object inside my Workers for Platforms, limit of 500 maximum durable object classes is not applied?

In other words, I can deploy unlimited number of Workers (for platforms) with DO class/namespace per worker. (unlimitted DOs)

When are we getting workflows?

Prydar•10/4/25, 12:24 AM

I’d like workflows too!

Hey everyone,

TLDR: How do I gracefully handle updating user workers in my dispatch namespace once they are already in production?
Note: I control the user worker code so every user worker will be THE SAME app just connected to different bindings instances

I am building a healthcare clinic management software and want to achieve the following architecture:

control plane worker where a user signs up their company
this kicks off a Workflow which provisions a tenant worker for that specific company alongside their own D1 database and R2 storage
the tenant is available via the subdomain pattern eg company1.example.com
the tenant worker handles its own authentication etc

I now have the subdomain based dynamic dispatch pattern working with a tenant worker that I have manually deployed

I have also successfully provisioned a tenant worker with its own D1 and R2 bindings via the Workers for Platforms Script Upload API

My question is if I make changes to the tenant app code and want to redeploy so that existing tenants will have the updated version of my application, how would I handle this in the cleanest way?

My solution I have thought of would be to store all the tenant names in a KV or D1 register and then in CI/CD I would loop through them and redeploy using wrangler

Is this the best option here or is there a more blessed path for this?

Thanks!

could you use http imports like deno does? not sure if they are supported. you'd suffer a small increase in cold start times though, but could probably layer aggresive caching around it using the basic cloudflare primitices

Prydar•10/9/25, 1:08 PM

built my first WfP tests today (based on getting started docs) - some observations - clicking on Dispatcher on dashboard errors out completely. Tags are cool, but no way to add/edit them with web gui. Very little observability of user workers. I'm clicking/reloading the demo "hello world" and the stats aren't updating on the user worker, but that could just be a delay thing.

Rafflesia•10/10/25, 2:38 AM

workers for platforms is fine but the dashboard UI for namespaces is pretty bad

Rafflesia•10/10/25, 2:38 AM

the regular workers UI in the dashboard is really nice, you can sort by requests and everything

Rafflesia•10/10/25, 2:38 AM

I really wish that same UI was in workers for platforms

PPeps Seems like they fixed that now https://developers.cloudflare.com/changelog/2025-...

Vlad Lykhonis•10/10/25, 4:59 AM

Interesting. I still see the issue, but will double check now. There is built in retry mechanism also in there, but it seems to fail regardless.

RRafflesia I really wish that same UI was in workers for platforms

Vlad Lykhonis•10/10/25, 5:02 AM

It is the same ui. When you deploy wfp enable observability in its settings. It will show up on the main ui

Rafflesia•10/10/25, 5:09 AM

as in its possible to get this UI

Rafflesia•10/10/25, 5:09 AM

for this?

Rafflesia•10/10/25, 5:09 AM

if so how do I enable observability?

RRafflesia as in its possible to get this UI

Vlad Lykhonis•10/10/25, 5:16 AM

I’m talking about observability page specifically.

To enable it for wfp specify it in metadata/settings when creating one worker or update it https://developers.cloudflare.com/api/resources/workers_for_platforms/subresources/dispatch/subresources/namespaces/subresources/scripts/methods/update/

I have a question on limits around workers for platforms

Can someone clarify whether we have account limits of DOs and workflows applied when using within wfp?

Rafflesia•10/10/25, 5:19 AM

^^ Same question here but also with D1

RRafflesia ^^ Same question here but also with D1

Vlad Lykhonis•10/10/25, 5:20 AM

Limits apply for D1 (50k per account).

Hi all -- trying to understand the WfP pricing. It says 1000 Scripts are included and then $0.02/Script afterwards. Is that per month? Or is that the one-time price of deploying one script?

Peps•10/10/25, 7:32 PM

monthly

Peps•10/10/25, 7:32 PM

there's an example pricing calculation at the bottom which confirms that:
https://developers.cloudflare.com/cloudflare-for-platforms/workers-for-platforms/platform/pricing/#example-pricing

Cloudflare Docs

Pricing

The Workers for Platforms Paid plan is $25 monthly. Workers for Platforms can be purchased through the Cloudflare dashboard.

Sean Dubb•10/10/25, 7:37 PM

I see, thank you.

Sean Dubb•10/10/25, 7:38 PM

Am I understanding correctly that any bundle of user code that my app deploys will cost $0.02/month even when completely idle?

Sean Dubb•10/10/25, 7:41 PM

I guess that would rule out Cloudflare as an infrastructure provider for a platform that wants to give its users the Vercel-like UX of deploying preview environments that stay up indefinitely

Sean Dubb•10/10/25, 7:41 PM

But let me know if I've missed anything

Doan | Full-Stack Developer•10/12/25, 2:45 PM

Hello guys.

Original message was deleted

Sean Dubb•10/12/25, 3:13 PM

Hopefully. I’d much rather pay to store my users’ bundles elsewhere.

$0.02/month is really very expensive compared to alternatives for this use case.

Peps•10/12/25, 3:14 PM

you could always put some custom logic on top that removes inactive workers and then cold-boots them in once visited again

Peps•10/12/25, 3:15 PM

not the most ideal, but might work in some cases where there's a lot of inactive workers

Sean Dubb•10/12/25, 3:17 PM

Yeah that’s a good idea. I’ve got something like that set up with Sandboxes right now, which I’m able to spin up pretty quick

Sean Dubb•10/12/25, 3:17 PM

How long does it take to deploy a fresh wfp worker?

Sean Dubb•10/14/25, 3:15 PM

Anyone know if the scripts billing is prorated? As-in, if I deploy a WfP script for 3 days, then delete it, am I charged roughly (3/30)*0.02 = $0.002(3/30)*0.02 = $0.002? Or will they charge for a full $0.02 for that script for that month?

Sean Dubb•10/14/25, 3:15 PM

The pricing page is a little ambiguous on Script pricing

Please do not ping community members for non-moderation reasons. Doing so will not solve your issue faster and will make people less likely to want to help you.

what is best practice for calculating hash for files in manifest?

King Kazu•10/20/25, 6:44 PM

there is little docs on if I need to match the hashing used by cloudflare, or if it doesnt matter as long as my hashing strategy is consistent in my application layer
